3. WORKING Hardware Components: Arduino microcontroller, GPS Receiver (SKG13BL), GSM module (SIM900A), optional 16x2 LCD. Functionality Overview: GPS Receiver detects vehicle coordinates, while GSM module sends coordinates to the user via SMS. Initiating Tracking: Send a specific SMS message (e.g., "Track Vehicle") to the system installed in the vehicle. Message Processing: GSM module receives the SMS and forwards it to Arduino. Arduino extracts the main message and compares it with predefined triggers. Response Generation: Upon match, Arduino extracts coordinates from GPS data and sends them to the user via GSM module. By following these steps, the system enables real-time tracking of the vehicle's location, providing users with accurate coordinates upon request via SMS.

5. Software Implementation Software Tool Used: Arduino Ide The Arduino Integrated Development Environment is a programming software that will be your interface between your Arduino board and the program. The Arduino IDE software has a compiler that will transform your program into a machine language understandable by the Arduino board.
